Abstract
The invention discloses a diesel engine fuel shut-off solenoid which comprises a shell, a coil assembly and an iron core. A front cover and a rear cover are arranged at the front ends of the coil assembly. The coil assembly is composed of an attracting coil and a keeping coil which are wound around a coil rack. A nonmagnetic guide pipe is fixedly arranged on an inner hole of the coil rack. The iron core is movably arranged on an inner hole of the nonmagnetic guide pipe. The iron core is provided with an inner hole and guided by a guide rod. The guide rod is fixedly connected with the rear cover. A reset spring is arranged between the iron core and the rear cover. The left end of the iron core extends out of an inner hole of the front cover and is fixedly connected with a pull rod connector. The left end of the front cover is fixedly connected with a sleeve. The diesel engine fuel shut-off solenoid is characterized in that the left end of the sleeve is connected with an adjusting nut cover in a threaded mode, an inner hole step is arranged on the adjusting nut cover, and under the effect of the reset spring, the portion, abutting against the inner hole step of the adjusting nut cover, of the pull rod connector is axially limited by the inner hole step. Adjustment during installation is facilitated, electromagnetic attracting force during work is higher, and the fuel shut-off reaction speed is effectively increased.
Description
Technical field
The present invention relates to be a kind of diesel engine fuel shut-off solenoid improvement invention.
Background technique
Diesel engine fuel shut-off solenoid is for controlling the throttle of diesel engine, and its working principle is: when diesel engine starts, coil electricity makes iron core action, and throttle is opened, and when diesel engine switch-off, iron core return after coil blackout, throttle is closed.The diesel engine fuel shut-off solenoid of prior art, adjustment during installation is not very convenient, and electromagnetism the suction-combining force during work is not very strong, and this compensates with regard to needing the diameter dimension by increasing iron core, causes fuel shut-off solenoid profile large.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide adjustment during a kind of convenient installation, during work, electromagnetism the suction-combining force is stronger, effectively improves the diesel engine fuel shut-off solenoid stopping oily reaction velocity.
The present invention takes following technological scheme:
Diesel engine fuel shut-off solenoid, comprise housing, coil block and iron core, the left end of coil block is provided with protecgulum, right-hand member is provided with bonnet, coil block, protecgulum and after be covered on housing endoporus carry out riveting by the turned welt at shell inner hole two ends and fix, coil block is made up of the pull-in winding of winding on coil carrier and keeping coil, the endoporus of coil carrier is fixed with non magnetic conduit, the endoporus of non magnetic conduit is located in described iron core activity, described iron core is provided with endoporus and is led by guide rod, guide rod is fixedly connected with bonnet, Returnning spring is provided with between iron core and bonnet, the endoporus stretching in protecgulum outside the left end of described iron core is fixedly connected with rod head, the left end of described protecgulum is fixedly connected with sleeve, it is characterized in that: the left end of sleeve is threaded with adjustment nut caps, adjusting nut is covered with endoporus step, under the effect of Returnning spring, described rod head leans and carry out axial limiting by endoporus step on the endoporus step of adjustment nut caps.
The just right end face of described iron core and bonnet has inner conical surface design, and the just right end face of described bonnet and iron core has male cone (strobilus masculinus) design, and inner conical surface is identical with the tapering of male cone (strobilus masculinus).
Adopt the diesel engine fuel shut-off solenoid of technique scheme, first, the position of endoporus step can be made to change by rotating adjustment nut caps, so the position of rod head is also just along with change, thus facilitating adjustment when diesel engine fuel shut-off solenoid is installed; In addition, the end face that iron core is relative with bonnet is the conical surface, magnetic strength area when pull-in winding is energized between iron core and bonnet electromagnetism the suction-combining force that is larger, iron core is stronger, thus effectively improve fuel shut-off solenoid stop oily reaction velocity, simultaneously, the diameter dimension of iron core does not need to change yet, and makes fuel shut-off solenoid compact structure.
Accompanying drawing explanation
The present invention has following accompanying drawing:
Fig. 1 is structural representation of the present invention.
